Sarah Greene and Peter Duncan

S6 E20: Blue Peter presenters Sarah Greene and Peter Duncan are on the hunt for antiques around Surrey, Hertfordshire and London. Peter detours to learn how hockey became a popular sport the world over, while keen aviator Sarah sees how the Battle of Britain was won. An incredible haul of antiques, including chimney pots, Pinocchio and a pair of African fertility figures, go under the gavel at an auction.
